UNITED STATES PATENT OFFrcE,

JOHN W. MALTBY, OF ROCHESTER, NEW YORK.

TRUSS- HOOP.

SPECIFICATION forming part of Letters Patent No. 240,435, dated April 19, 1881. 7 Application filed January 20, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN W. MALTBY, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Truss-H oops, of which the following is a specification.

My invention relates to truss-hoops for coopers use; and it has for its object the production of a truss-hoop the laps of which shall be so riveted that they will not draw apart nor split, and the irons so applied that they will not come on the inside of the hoop.

The invention consists in securing the laps of the hoop by diagonally-bent binding-irons riveted to the sides and periphery of the hoop by rivets passing through its ends and center, the center rivet passing through the hoop between the two rivets, securing the ends of the irons, and at'right angles to them.

In the accompanying drawings, Figure 1 is a plan view of my improved hoop. Fig. 2 is a. front view of its periphery; and Fig. 3 is an enlarged view, showing one of the bindingirons and the rivets passing through it.

Similar letters of reference indicate corresponding parts.

The hoop A is formed in the ordinary manner, with the ends A A lapping each other, as shown. The binding-irons B are bent so as to clasp the sides of the hoop and pass diagonally across or over the periphery of the hoop, and they are each provided with a rivethole in each end and a rivet-hole in the center.

The rivets O 0 pass through the hoop from opposite directions and through the rivet-holes in the ends of the binding-irons B, and are headed to secure them firmly to the sides of together without the necessity of weakening the end of the inner lap by embedding a binding-iron in it, as heretofore, and the rivets are so placed in relation to each other that the ends of the laps are prevented from splitting.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- In fastenings for the lapped ends of trusshoops, the combination, with the irons B, clasping the sides of the laps and passing diagonally over the periphery of hoop, of two rivets passing in opposite directions through the ends of each iron and through the sides of the underlap, and a third rivet passing from the periphery of hoop down through the middle of iron and through both laps, as shown and described.
